WASHERjPLACING MACHINE FOR RUBBER-HEEL MOLDISL Appncanon med Maren 2, 1925.` seriar No. 12,636.

To aZZ whom it may concern.'

Be it known that ROBERT T. TUCKER, a citizen of the United States, residing at Royston, inv the county of Franklin and State of Georgia, has invented certain new and. useful Improvements in a Washer-A Placing Machine for Rubber-Heel Molds, of which the following is a specification.

The presentinvention appertains to a mav chine for placing the washers in the mold for a rubber heel.

The principal object oi' the machine is to provide a labor saving device which in a Single operation will properly distribute the washers in the molds. v

Another important object o1 the invention is'to provide a machine embodying a feed structure having a hopper-Vin which a supply of the washers may be carried and properly fed to the machine so asto .be distributed in the mold thereby.

Another important object of the inven tion is to provide a machine of this nature having means incorporated therein for properly centering the washers and guiding them as they fall from the machine into the mold.

A still further important object of this invention isto provide a machine. of this nature having an extremely simple and etticient structure, one which is fairly reliable in operation, capable ot' being manufactured at a comparatively low cost, not liable to readily get out of order, durable, light, and' otherwise well adapted to the purpose for which it is designed.

W'ith the above and numerous other objects in view which will appear as the descriptionproceeds, the invention resides in certain novel features of construct-ion, and in the combination and arrangement of parts as will be hereinafter more fully 'described and claimed.

In the drawing, Figure 1 is an elevation of the machine embodying the features of my invention,

Fig. 2 is a vertical section therethrough,

Fig. 3 isa horizontal section taken sub-v stantially-on the line 3-3 of Fig.1 looking downwardly,

Fig. 4 is a bottom plan view of the ma.- chine,

Fig. 5. is a detail vertical section taken substantiallyl on the line 5-`5, ofpFig. 3 looking in the direction of the arrows.

Referring to the drawing in detail it will be seen that 1 designates a rubber heel mold of conventional construction having the Abottom strips 8 therebelow and strips 9 rest-l ing on strip 8 and spaced below the plate 7.

This base 5 including the plate 7 and strips 8 and 9v may be made integral if so desired. lVa'sher receiving tubes 10 rise from the plate 7 and are equal in number to the number of vthe washer receiving elements 3 in the mold with which the machine is to be used. These-tubes 10 are arranged .in substantially the same rnanner'on the plate 7 as the elements lare arranged in the mold, however,

-the tubes 10 are not arranged in alinement with these elements but rather to one. side thereof as is indicated in Fig. 2- for a purpose which will be evident as the description proceeds.

Guide tnbes11 also rise from the plate 7 and one tube11'is arranged' in close proximity to each tube 10. The `tubes 11 are vertically alined with the elements 3 'in the mold as is evident from an inspection. of Fig. 2. The tubes 10 and 114 communicate with the sp'ace below the plate 7 by the provision of suitable openings therein of equal size with the bores of these tubes.

It is preferable to permanently attach the. tubes 10 and 11 to the plateialthough" this does not form an construction.

v A plate 1'2 is provided with a plurality-of openingsv lgffand 14. The tubes. l10 roject through the openings 13 so that the plate is slidable on these tubes toward and away froi'nfthe base 5. Suitable handles 15 essential feature oit 'my are provided on the opposite .edges of the.

plate 12 for manual/actuation thereo. "A i .standard 16 rises perpendicularly from lthe base 5 and extends through a sleeve 17 provided in an intermediate portion of the plate 12 and disposed perpendicularly thereto.

This sleeve 17 slides=over the standard 16v and forms the main 'guide forthe' plate. 12. A coiled spring .18 is disposed about lthe standard lfand about the l'o'wer portion of in a manner which is het-Ween the plete is evident from un inspection oi Figs.

, When'the plate the sleeve l? and impinges against the bot tom of the plate 12 and the top of the plete 7 of the buse 5 plate l). in its uppermost raised position in relation to the plete "i". A hopper is supported above the plete IFJ by leg.. 2i or in any' other suitable manner. This hopper 2O is provided ivillha bottoni guide portion Q2 having formed therein guide tro ughs 23 'terminating in cylinchicu portions Which slidably receive the 'upper portions of sthe tubes l0. This hopper is in be lilled 'with a supply oi the conventional forni of washers which will he Tied into the tubes l0 quite evident from en inspection of Fig. 2 end will become even more evident as the operetion of the me chine is hereinafter explained.

. plate 2d is slidohly mounted in hes end strips Si and o; is slideble between the plate 24 strips 8. The e i ihe plete. along es of lil` the inner longitudinal o the strip 9 being' in the suine plone therewith as Q and '1, end this pluteprojccts beyond one side of the base es is indicate-d to advantage in both A Figs. l end fi.

pin sind slot connection is formedbetvveen the plete?, and 2a? is moved in one direction the plete 25 `vill be moved in e directionnt right ongles thereto. This pin and slotlcon` neetion may best be understood 'oy en' in- L spectionoi Figs. 2 und Ll. wherein it will he seni that in the resent orme ement e sul nelly trionguinr shaped slot is rovided in the plete 25 having the slantmg, oclined, or com? edge 28 engagceble hy e pin ejected from the plete 24C. A pair oi' O rief ""orn the outer end of the plate sin'Liln-r pair oi lugs 3l rise from 'the base 5 and springs 32 connect the lugs and 31 'and normally urge the plate 25 inwardly so that when the plete 2i, :is shown in i is :fnoved to the left. the springs 83 'will move the plate 2o' toward the bottom 01'" said figure during' which operation the pin moves :along the inclined edge 28 oi slot New reihen the plete moved to the righi, still referring to Fig. the pin 29 will .nieve elche; the inclined edge 28 and move the plate 25 toward the top of seid figure or outwardly thereby placng the springs under further tension.

Theplete 25 is provided with plurality ot o cular openings 534e having redielly er@ fendi.. slots The-.plete is provided 7with 1plurality oi circular openings The openings 34 and 36 are arranged in their respective plates in e manner similar to the arrangement oi.2 thetubes l0 on plete 7 and the openings El() ere normally in regis try Withthe tubes l@ is indicated in Fig. 2 'while the openings Se are normally' out of register with. the openings end tube l0.

so es to normally hold the' so that l 'ot this invention have now 'plete 2 has pro Lessons plurality of pins 38 project` through the plete 12, one adjacent each tube -lO und springs 39 ere connected at their bottom ends tothe plete 1Q und at their top ends 'to the top ends o1 the pins 38 and the bottom ends of these pins 38 project into the guide tubes ll.

)y referring particularly to Figs. 3 and 5 it will be seen that o pair of standards el()y rise from the lplate 24 and project vertically through the elongated slots lll in plate 7 and through similar slots 42 in pla-te 12. Adjacent the upper ends of these standards there are provided slanted, beveled, or com. edges to be engaged by rollers fifi jouriuzled on top of the plate 12, one at the 'end of each slot 42. .lt will thus be seen that when the handles l5 are pushed. downwardly end the plete l2 therefore .moves downwardly, the rollers 44E Will engage the incinededges 43 so es to move the standorde 4.0 and 'the plate 24, this movement of the plete to the left as illustrated ieg previously referred 'to in describing the operetion of plate 24.

A stop lug 46 is provided on the outer portion of the plate 25 and is normally enraged by o. spring normelly'holds the plete in its outwardly extending position as illustrated inFig'. l.

.The details of the preferred embodimentI m been described sufiiciently in order that its operation may he clearly understood.4 The Washers are poured into the hopper 2O until the same is illled or contains a desired number end' the machine is ready for operation. The Inen chine is placed over the mold l and the guide apron 6 will properly center the suine on the mold so that the tubes 1l `erre vertically alined with the washerreeeiving elements '3. `When in this position' the hendles 15 are pushed downwardly at which time the plate l2 moves 0downwardly und the rollers 44 thereon eugene the inclined edges 43 of the 'standards si() thereby sliding plate 24, it being' understood, of course. that there' is a Washer located `in each opening'36 of this plate 2i having been delivered thereto through the-tubes 10 bymee'ns of gravita.- tion. These Washers which 'are 'now located in the openings Srest uponthe: plate 25 which will -remanstationary unti tbe seed considerably.

ther and allow the release rod 38 to actuate the dog 47 out of engagement'with the stop 46. As soon as the dog 47 is released from thestop 46 the springs 32 move the `plate inwardly of the base 5 because of the movement of the pin 29 previously by the plate24and the 'openings '34 come into registry with the openings 36 and the washvers are free to drop onto the elements A3. In this connection it is to be noted that the slots allow the ins 38 to be projected downwardly theret irough as soon as the openings 36 in the plate 34 are moved over --l'ln registry with the tubes 11 and elements 3, this bein true because; the springs- 39 are st'retche o1" under tension as lthe plate l2 is moved downwardly and the lower ends of the pins SS'engag-e the plate 34 because" Y projecting through the openings in the washers and'when engaged in these openings of the washers, they project downwardly and engage with the tops of the elements l.3 an

the springs 39 fare further tensioned 1 as the plate 1 2 is further moved downwardly so as to'allow the releasing rod 48 to eni' gage `the dog 49,

I t is thought that the construction and operation of the inventionvr should no-w'be lclearly understood without a more detailed description thereof.

.It vwill be apparentL from the above *thatv I haveY devised a very. eiiicient machine of .this nature which is fairly' reliable for the purpose designed and"t`hat it is efficient in its operation, not liable pable 'of being manufactured at a relatively low costin comparison to the Iamount of la- `hoi' saved thereby. It will alsobe apparent. that I have obtainedall of the .fea--- tures of advantage enumerated as desirable b in the statement of the invention, and

vvthat numerous changes in the details of construction, andL in thecombination and arrangement of parts may be resorted to without departing' from the spirit or scope of the -invention `as hereinafter claimed orv l 25 will be extended to its normal position lacing the springs`32under tension and allhwlng the stop 46 to be again engaged oy the dog 47.
